Resources Evaluation Of Shale Oil In Damintun Depression Shahejie Group

Conventional oil and gas continue to reduce, making unconventional oil and gas in the energy has become an important research area. As the representative of unconventional oil and gas, the enrichment degree of shale oil and the evaluation of the recoverable resources amount become more and more important. In Damintun Sag, there is a wealth of unconventional oil and gas.In this paper according to the Liaohe oil field to provide a Damintun Sag Shahejie group of old wells data research and analysis, the shale oil and gas resources in the region were evaluated. There are many methods for the evaluation, according to the analysis results, the evaluating method of made one by one comparison, in Damintun Sag has been screened out the most suitable evaluation method- volume method, and according to the data to determine the grading evaluation criteria of shale oil and gas resources.Analysis of the key parameters of the grading evaluation of shale oil and gas resources; according to the data of old wells draw different levels of thickness of shale, TOC, S1, chloroform bitumen "a" contour map, the classification evaluation of shale oil and gas resources; to establish the model of TOC, S1, chloroform bitumen "a", make shale organic heterogeneity logging evaluation. Through Shahejie formation oil shale research and evaluation of Damintun Depression, dividing the favorable target zones, of the target zone of shale oil and gas movable, mining resources were evaluated. Damintun Sag E2S34 no movable, recoverable amount of resources about; E2S41 movable resource amount is about 13 million tons; E2S42 movable resource amount is about 0.31 million tons. Damingtun sag shale oil recoverable reserves of about 0.11~0.14 million tons. The E2S42 is favorable area in Damintun Sag, mainly concentrated in the vicinity of Shen 224 and shen 223 two wells.
