Pore pressure is essential data in drilling design, and its accurate prediction necessary to ensure safety improve efficiency. Traditional methods for predicting pore are limited when forming particular structures lithology. In this paper, a machine learning algorithm effective stress theorem used establish the transformation model between rock physical parameters pressure. This study collects from three wells. Well 1 had 881 sets training, Wells 2 3 538 464 testing. support vector (SVM),...
Natural gas hydrate reservoirs have low permeability and uneven distribution, necessitating multiple branches for effective commercial development. Due to cost technical constraints, multi-branch horizontal wells typically forgo packers in previously drilled sections, relying instead on intelligent completion technologies flow control devices. This paper investigates the complex multiphase of drilling fluid rock cuttings annular spaces during wells. A simplified model Euler are used analyze...
During the drilling of natural gas hydrate reservoirs, invasion may occur, which has an adverse impact on upward return process cuttings and control bottom-hole pressure. A multiphase fluid CFD simulation method based Eulerian model was optimized. With help Fluent 23R1 software, simulations three-phase flow fluid–cuttings–invaded in vertical section, build-up horizontal section complex annulus wellbore particle dynamics were carried out. The characteristics after revealed, impacts deposition...
The diagnosis of overflow risk has always been an important area research in drilling operations the field oil and gas engineering. In face limitations lag traditional methods, practical application effect existing models methods is not obvious, there no integration physical model intelligent algorithm for diagnosis, this paper proposes a method adaptive weight fusion results. Based on model, managed pressure established. results show that can combine accuracy risk, which improves...
Formation pore pressure is one of the most important basic data in petroleum exploration and development. The traditional prediction model formation relies on artificial experience highly subjective, so it seldom considers influence multiple variables characteristics pressure. In recent years, machine learning has been applied lithology, reservoir, complex drilling conditions, pressure, other fields. This article introduces research progress general process algorithm years. this study,...
Traditional annular laminar flow analysis method applied in drilling engineering has poor accuracy and does not apply to complicated rheological models. A general of calculating pressure drop fluids with different models was proposed, compared traditional method, verified using experiment data published articles. Based on slot model, the pipe equation popularized an established, relationship between shear stress at wall established by combining fluid's equation. If is given, can be got, then...
Extreme storm-safe drilling riser, a solution to overcome high time cost of riser emergency retrieval under the situation imminent typhoon arrival, is modify existing make it disconnectable and leave long string below in freestanding mode survive. The buoyancy can maintains neutral during normal operation. However, locally will have some effect on system nearby. Numerical analysis hybrid scaled truncated model test water tank are conducted for two critical configuration modes: connected...
Abstract In modern warfare, artillery systems serve as crucial equipment, and their firing accuracy directly impacts overall capability to strike targets. Especially under local warfare conditions, the demand for shooting of large-caliber small-caliber naval guns is increasingly high. This paper focuses on interior ballistics design by constructing an accurate model projectile’s in-bore motion.
To improve the comprehensive experimental skill of undergraduate and penetrate concept green chemistry education, we combined with teaching needs applied designed a experiment preparing drilling fluid treatment agent waste citrus peel as raw material. Citrus fruit contains lot plant phenols, cellulose, soluble polysaccharides other components, which can be used to increase viscosity reduce filtration loss. However, proportion water-soluble substance in is low effect poor. Therefore, its...
Abstract Since depth of shallow layers in the deep water is general 1500 ft or more, temperature approaching freezing point at this depth. Moreover, Drilling Fluid always has a high which can lead originally stable gas hydrate, flow and to disorders, for example, corrosion deformation drilling strings, blowout pipeline jam be induced by flow, natural hydrate respectively. This paper conclude new method describe complex gradient layers. A model heat transmission about including wellbore...
The composition of tuffaceous sandstone is complex, and it easy to react with CO 2 , resulting in significant changes wettability during CO2 flooding.However, the change mechanism for still unclear.Therefore, researches are carried out laboratory study flooding a reservoir.A high temperature pressure reactor used establish reaction environment -waterminerals, maximum 65℃, 20 MPa.The wettability, mineral morphology reservoir rock samples were measured by contact angle meter, EDS energy...
