Construction Accidents

In the past decades, horizontal directional drilling (HDD) has been successfully used to install various pipelines in different strata. However, construction accidents such as drill-burying and drill-sticking occur occasionally when pipelines installed by HDD method in an unstable stratum such as sand cobble stratum. Recently, HDD with dual drill pipes was used to install pipelines in unstable stratum, and the effect is significant. The law of cuttings migration for HDD with dual drill pipes is still unclear. Therefore, it is necessary to study the law of cuttings migration in reverse circulation with dual drill pipes. This study performs numerical simulations and experimental research on the cuttings-carrying process in reverse circulation directional drilling with dual drill pipes. Based on the assumption of dual concentric pipes, simulations of fluid-solid two-phase flows are conducted in different flow channels between the inner and outer drill pipes. An experimental cuttings-carrying model is then established. By combining the results of the numerical simulations and experimental investigation, the hydraulic parameters of the dual drill pipe system are optimized, and the rationalities of the drill tool design and the grading selection are validated. The results of this study provide a reference cuttings-carrying model during reverse circulation HDD with dual drill pipes.

Access Efficiency

Sea or land rig requires a lot of roots in the drilling process. The catwalk-machine generally transports drill pipe to the second floor units. The rooted is established by dynamic rat holes, stored in boxes and taken from the rooted box during the drilling process. Automatic control systems for the rig on the stand of emissions complete automatic access of rooted. Previous control systems adopt the method of fixed access in order to complete the order for reducing control, although such control program is simple but the production efficiency is not high. In this paper, to access the walking path [1] in the process of the minimum as the optimization goal, not to block the internal root deposit box for qualification, designed a control algorithm to optimize the access path, which greatly improves access efficiency, reducing the distance of sports equipment, with high practical value.

Abstract This article is a description of a comprehensive engineering approach to new designs of PDC (Polycrystalline Diamond Compact) Bits and bottomhole equipment for efficient horizontal wells drilling in the Yamal-Nenets Autonomous Okrug (YNAO) fields with Rotary Steerable Systems (RSS) Point the Bit (PTB) type. The paper represents an analysis of the efficiency of drilling rocks of various hardness depending on the bits, the bottom hole assembly (BHA), and type of vibrations. In the Yamal region fields a main constraint of sub horizontal sections drilling performance for liner run in hole is the occurrence of vibrations. The predominant vibration types are Stick and Slip (S&S) and High Frequency Torsional Oscillations (HFTO). These types of vibrations often had to be reduced by limiting drilling regime (weight on bit (WOB), drill pipe (DP) RPM, and flow rate), which directly affected on the rate of penetration (ROP). To find solutions to this problem for drilling performance improvement, geological and geomechanically modeling of rock properties and an analysis of burst-files of vibrations (modeled in specialized software) were carried out based on downhole data. The studies have found key factors that cause the high vibration impact and reasons for premature wear of the PDC bits, which served as a basis for identifying the shortcomings of previous bit designs. Test beam experiments were also performed to assess the bits wear while drill-out of the casing accessories. The results formed the basis for development of new PDC bits designs using specialized software. As an output new 155.6/152.4 mm bits designs with an innovative cutting structure that considers the geological features and technical aspects of drilling liner sections in YNAO fields were manufactured. The new bit designs have significantly reduced vibration levels, improved ROP performance in the liner section using RSS PTB, and decreased the overall well construction time. These solutions open wide opportunities for their further implementation on other projects both in Russia and in other CIS countries.

Swamp drilling operation in Mahakam has entered the industrialization period in which fast drilling is a common practice. However, fast drilling Rate of Penetration (ROP) causes hole cleaning issues to arise and induce a high Equivalent Circulating Density (ECD) trend. In some wells, this potentially leads to loss problems because of weak formation in shallow sections or depleted formation with relatively low fracture gradient. As a result, drilling parameter reduction was performed that causing lower ROP and additional circulation to reduce ECD. A new technology called Continuous Circulation Device (CCD) can help to tackle the problems mentioned above. It is a sub-based constant circulation system that enables the continuous circulation of drilling fluids downhole while making or breaking drill pipe connections. This system helps to maintain ECD and improve drilling performance as the cuttings are continuously carried out of the hole. This paper is introduced to analyze the benefits of CCD and opportunities for future development in the swamp drilling operation. The device was applied during drilling in the 12-1/4” and 8-1/2” sections. The challenge during drilling in these sections was to improve ROP without inducing bad hole cleaning that could lead to a high ECD trend. The result of CCD utilization shows that ECD during drilling could be reduced up to 2 points and become more stable compared to the previous trend. Since there was a reduction of ECD, the ROP could be improved up to 10%. Furthermore, only 1 cycle for circulation at well TD was performed as the minimum cuttings appeared. Pulling out the string and running the casing string was managed smoothly as the hole was already in a good condition. This utilization has been successfully implemented without any safety incident nor related Non-Productive Time (NPT). This positive result leads us to open the opportunity for future development in swamp fields asset.

The finite element analysis provides a simple effective method for the design of the structure of the mechanical clamping claw. Through this device the drill pipe can be transferred automatically and circularly from the rat hole to the pipe racking system and from pipe racking system to the mouth of the well.
