The Relationship

As an important yardstick of water quality evaluation, total dissolved solids (TDS) is strongly correlated with apparent resistivity and static spontaneous potential (SSP) parameters from electrical logging curves.A lot of electrical logging data accumated in the hydrogeologic survey during last decades can be used to predict the underground water TDS. Based on electrical characteristic analysis of sandstone reservoir, taking the influfential factors of the Archie’s Equation and creation mechanism of spontaneous potential (SP) as starting points, the theoretical relationship between the underground water TDS and formation resistivity (Rt) without considering the infuence of the porosity is modeled in this paper, and also the relationship between the underground water TDS and SSP in the same section of drilling well. Utilizing the apparent resistivity logging and static potential logging data, and employing the numerical fitting method, the relationship between groundwater TDS and conductivity is analyzed and determined, finally, the electrical parameters of determining the water quality and the regional evaluation of water quality are expounded in Daqing oil field,songliao plain Quaternary sandstone aquifer.

Abstract A water treatment pilot skid called WaOω has been developed by TotalEnergies to test the efficiency of the centrifugation technology in treating the produced water containing back produced polymer. In case of success, this technology would be implemented on field and the water quality targeted by the technology must allow re-injecting the treated produced water in matrix flow regime for pressure maintain and sweep efficiency. The same interest was expressed by OMV and a partnership project has been built. It was also agreed that OMV builds a second pilot skid called PRT that allows carrying out core flood tests onsite to assess the formation damage and related permeability decline that could be induced by the treated produced water. Both pilot skids have been implemented, connected to each other, and tested during more than one year on the OMV's Matzen oil field nearby Vienna where degraded polymer is already back produced by wells and present in the produced water. More than seventy core flooding tests have been performed in different centrifugation conditions in terms of speed and water qualities, some of them on high permeable sand packs representing the field targeted by TotalEnergies and some others on consolidated sandstone samples of lower permeability representing OMV reservoirs. The effect of adding fresh polymer to the treated produced water for EOR purposes has also been investigated. Some complementary core flood tests have also been performed in TotalEnergies labs using reconstituted sand packs and produced waters with and without polymer to understand the contribution of the degraded polymer alone, the produced water quality alone and both to understand the formation damage and some uncommon results observed with the PRT pilot skid. Core flood tests data often obtained on long injection periods revealed of a high quality, reliable and reproducible. They also showed that even if centrifugation seems to be a good technology, the very clean and transparent water that it delivered induced surprisingly some core permeability declines the origin of which would be discussed in this paper. However, it was clearly established that the presence of degraded polymer has a cleaning effect and limits the formation damage induced by the produced water injected on cores if the Total Suspended Solids in the treated water remains at an acceptable level. Adding fresh polymers limited even more the formation damage because their cleaning effect is more pronounced than with degraded polymer.

High Removal Rate

According to the problem of polymeric compound appearing in oil field produced water, following by the changes of water quality characteristics that result in the polymeric compound accumulated in the filter tank which lead to the poor regeneration, being partly hardened and the losing, and the over standard of water quality, the study uses the technology of axial dynamic backwashing to back wash and regenerate the dual-media filter of walnut shell/quartz sand. The removal rate of oil content for filter materials reaches above 90% after backwashing. Simultaneously, cleaning the granular filter materials in filter bed achieves high removal rate of oil and suspended substance content, the average removal rate of oil content being 96.0% while the suspended substance 77.81% which greatly improved the water quality index.

Wireless Sensor

In these years, petroleum and natural gas exploitation cause underground water pollution worldwide. And the leak of the crude oil and injection of waste water in the fracking process are two main reasons of water pollution during the exploitation. So monitoring the water quality in petroleum and natural gas exploitation area is more and more important to assure the drinking water’s safety for people who live nearby. In this paper, a wireless sensor system for water quality monitoring based on wireless sensor networks (WSNs) is designed. This system uses XBee modules as the communication units and chooses proper sensors to monitor the key parameters for water quality including PH, turbidity, conductivity and temperature. And we also use LABVIEW to build an interface to monitor, restore and analyze the data collected.
