中文摘要：
岩石的强应力敏感性和启动压力梯度是低渗透变形介质油藏开发中必须考虑的基本特征。塔中11区属于低渗透薄互层底水油藏，确定合理的水平井生产雎差可以保证较高的产能和最终采收率。由于该区低孔低渗、垂向渗透率差，考虑强应力敏感性和启动压力梯度，从泵效最大、发挥储层潜能最大和抑制底水锥进的角度分别求取了合理生产压差，最终确定了TZlllH井的合理生产压差，对油田实际生产有一定的指导意义。
英文摘要：
Strong stress sensitivity and kick off pressure gradient of rock are the basic features that should be considered in the development of low-permeability deformed media reservoir. Block Tazhong 11 belongs to low-permeability thin-interbed reservoir with bottom water, and the determination of a rational producing pressure difference is the guarantee of high productivity and ultimate recovery factor. Due to the low porosity and permeability and poor vertical permeability, considering strong stress sensitivity and kick off pressure gradient, the rational producing pressure difference is calculated in view of developing the oil layer to the fullest extent and restraining bottom-water coning. At last, the rational producing pressure difference of Well TZ111 H is determined. This is significant for the guiding of actual production in oilfield.
