The ROP (rate of penetration) within the horizontal section shale gas wells in Luzhou oil field is low, seriously delaying exploration and development process. It proved that reducing mud density mitigates bottom-hole differential pressure (ΔP) increases during overbalanced drilling. However, wellbore collapse may occur when excessively low. urgent to ascertain optimal equilibrium point between improving maintaining stability. safe weight window lower limit block are predicted using...
Borehole instability in naturally fractured rocks poses significant challenges to drilling. Drilling mud invades the surrounding formations through natural fractures under difference between wellbore pressure (Pw) and pore (Pp) during drilling, which may cause instability. However, weakening of fracture strength due intrusion is not considered most existing borehole stability analyses, yield errors misleading predictions. In addition, only limited factors were analyzed, distribution was...
Summary Fracability characterizes the ease of gas shale to form a complex-fracture network with hydraulic-fracturing treatments. Previous methods fracability evaluation take into account some mechanical properties shale, such as brittleness and fracture toughness. However, very little work has been performed verify these by comparing predicted against actual result fracturing stimulation. Moreover, prediction models toughness used in previous are derived from conventional rather than which...
In recent years, there has been significant research and practical application of machine learning methods for predicting reservoir pore pressure. However, these studies frequently concentrate solely on blocks exhibiting normal-pressure conditions. Currently, exists a scarcity addressing the prediction pressure within characterized by abnormally high pressures. light this, present paper introduces learning-based approach to predict The methodology is demonstrated using X block as case study....
The conversion of abandoned butted well salt cavities into underground storage facilities holds immense significance for safeguarding energy security and improving the ecological environment. A significant barrier to reconstruction these old is limited comprehension their complete morphology, caused by residue coverage. three-dimensional seismic techniques excel in identifying complex geological structures but have a understanding cavity thus forward simulation method utilized study response...
Salt-cavern underground gas storage is technically faced with non-uniform distribution of stratified salt rocks, complex solution mining mechanism, difficult control process, less operation safety and stability caverns reconstruction utilization old caverns. In view these technical difficulties, the design concept was fully updated based on experience field practice Jintan in Jiangsu, for purpose maximizing layer ratio, improving efficiency, shortening construction time ensuring cavity...
