The exploration of mid-deep oil and gas is constrained mainly by reservoir petrophysical changes of deep Dongying and Shahejie Formations. 辽中凹陷沙河街组及部分东营组储层埋藏深度大及储层物性变化大的特点制约了中深层油气的勘探;
This technology can be used not only in mid-shallow casing failure wells, but also in mid-deep casing failure wells. 该项技术不仅适用于中浅层的套损井,也适用于中深层的套损井。
The analyzed result shows that distinct velocity layering feature occurs in vertical direction, and velocity reversion is found in near surface-shallow zone and mid-deep zone; 分析结果表明,本区速度纵向上成层性较明显,在表层-浅层段及中-深层段存在速度倒转现象;

Conceive of Mid-deep Hole Format Cut Parvis 中深孔形成切割天井的设想
Based on practical working, we have proposed a set of technologies and methods suitable for the reservoir predication in the mid-deep Paleogene, including continental sequence stratigraphy, palaeo-geomorphology, seismic facies association seismic attribute interpretation and diagenetic dynamics. 基于工作实践,提出了适合渤海古近系中深层储层预测的技术思路与方法,包括陆相层序地层分析、古地貌分析、地震相组合与地震属性解释以及成岩动力学分析等。
With the mid-deep massive heavy oil reservoir in this oilfield as an example, reservoir geology, reservoir engineering, drilling, oil production programs and the main problems existing in field operation are systematically analyzed, and the technical countermeasures for improving steam drive development response are proposed. 以高升油田中深层块状稠油藏为例,系统分析了油藏地质、油藏工程、钻采工艺等方案设计及现场实施存在的主要问题,提出了改善蒸汽驱开发效果的具体技术对策。
Fracture Identification of Mid-deep Reservoir in the Middle Section of Western Sichuan Depression 川西坳陷中段中深层致密储层的裂缝识别
So it is doubted that the industrial scale oil come from the mid-deep level because of the leaky casings. 以前浅层的试油结果表明仅有油显示,但没有工业油流,因此怀疑该井所产原油因油管泄漏而来自中深部。
The genesis and evolution of secondary pore development zone is important basis for the high-quality reservoir evaluation and the deployment of oil and gas exploration in mid-deep formation. 次生孔隙发育带的成因及演化是中深层优质储层评价和油气勘探部署的重要依据。
So the research on the genetic mechanism and evolution model of secondary pore development zones has great leading significance in theory for oil and gas exploration in mid-deep formation. 因此,开展次生孔隙发育带成因机制及演化模式研究对中深层油气勘探具有重要的理论指导意义。
