Oil And Gas Drilling

The oil and gas industry places higher demands for new technologies and new materials. Advanced functional materials show broad application prospects in the oil field. Technological advances in the oil and gas sector are inseparable from the development and application of advanced functional materials. Through literature research, patent search analysis, expert consultation, some advanced functional materials with potential application in the oil field are sorted out, in order to provide inspiration and new ideas for improving the development of the oil and gas drilling technology. The nanomaterials dispersion and nanocomposites films are two of the most accessible ways to apply nanomaterials in the oil field. The cellulose nanofibers (CNF) and the diamond-like carbon (DLC) nanocomposites films would provide inspiration for the oil field chemistry and protection of downhole tools. The application of CNF and DLC nanocomposites could provide innovative ideas, research and foundation for the future development of the oil and gas drilling technology, and contribute to achieving a major technological breakthrough and improve the overall level of the oil and gas drilling technology.

Supercritical Carbon

Some novel drilling technology has promoted the exploration of unconventional oil and gas resources greatly, such as gas drilling, long horizontal section well drilling and so on. As special matter, Supercritical carbon dioxide has many useful characteristic. For example, relative higher gravity like water, lower viscosity like gas and wonderful crude oil displacement characteristics, these could play some important role if being used in exploration of unconventional oil and gas. Therefore, the feasibility study of supercritical carbon dioxide drilling technology and equipment matching plan are discussed in this article to make the preliminary studies and preparation of related technology. On the basis of a lot of research and study, This paper carries out a feasibility study of supercritical carbon dioxide drilling equipment.

Absorbent Polymer

Gas drilling technology have very distinct advantages, it can improve ROP greatly, shorten the drilling cycle, reduce drilling costs, but it's scope of application was greatly limited by the problems of formation water and wellbore stability. This project developed a kind of super-absorbent material which can absorb deionized water 1484 times,absorb 0.9% NaCl aqueous solution 687 times,absorb 50% ethanol 705 times, that can meet the water carrying requirements of gas drilling. it provides a new way of gas drilling to solve the water carry problem.

Drilling Technology

The gas drilling mainly relies on the high speed air flow to carry the cuttings. The formation water or oil mixed with the cuttings and then they stick together in clumps after the formation water or oil went into the hole annulus, the clumps stick on the drill string and the borehole. The clumps may block the hole annulus and cause the stick or bury the drill string and many other complex accident. It could stop the cuttings from sticking with the liquid through freezing the formation fluid with the liquid nitrogen. And the natural geotechnical becomes into the frozen soil, and forms the temporary solid which is intact, high strength and low-permeability. In this paper, according to the characteristic of the gas drilling technology, we optimized the scheme of freezing technology for borehole stability to give the theoretical basis of the industrial application.

Selection Of

In carboniferous system of Dzungaria basin, the hard igneous rock greatly decreases the drilling velocity. Gas drilling is probably the only technology to overcome this problem. However, the applicability of gas drilling technology should be investigated first. It was studied by analyzing the rock strength both experimentally and theoretically. Stress status of many rock elements near well face was tested which showed a 2D compression status rather than 3D in conventional slurry drilling technology conditions. Therefore there was a horizontal stress for underground rocks, in a similar magnitude with upper burden pressure. The domination of the confining pressure, different with normal conditions, may mislead the selection of the failure criterion. We proved the correction of the Mohr-coulomb criterion as the most suitable failure criterion in gas drilling conditions. As a result, the applicability of gas drilling technology in Carboniferous system of Dzungaria basin was concluded.
