A油田加密技术研究与效果评价

A Oilfield Encryption Technology Research and Effect Evaluation

"十五"以来,逐步形成了A油田不同类型区块加密调整技术,有效地改善了区块开发效果。但各加密区块加密效果存在差异,因此有必要对各加密区块的效果进行综合评价,并根据存在的根本问题,制定有针对的治理对策,进一步改善加密区块效果。通过对加密区块的井网适应性、开发效果、经济效益等方面进行综合评价,加密区块的加密效果进行综合评价,并制定了区块下步治理对策。

Since the 10th Five-Year Plan, it has gradually formed the encryption and adjustment technology of different types of blocks in A oilfield, which has effectively improved the effect of block development.However, there are some differences in the encryption effect of each encryption block.Therefore, it is necessary to evaluate the effect of each encryption block comprehensively. According to the fundamental problems, the countermeasures are put forward to further improve the encryption block effect.In this paper, the adaptive evaluation of the well pattern, development effect and economic benefit of the encrypted block is carried out.The Fisher and Bayes method are used to evaluate the encryption effect of the encrypted block, and the countermeasures are put forward.
