摘要： A system and method for removing particles from a well bore penetrating a possible hydrocarbon producing formation, according to which drilling fluid is mixed with a weighted material, and the mixture is introduced into a well bore so that the mixture scours any particles accumulated in the well bore. A well-completion fluid is introduced into the well bore that dissolves the weighted material.

摘要： The hydrophobic, rheologically effective products, based on clays and/or clay minerals with ion-exchange properties, contain quaternary ammonium ions of general formula (I) as cations for generating hydrophobicity, where R1 and R4 may be chemically similar or different and may be a hydrogen atom, a straight-chain or branched, cyclic or heterocyclic, unsubstituted or substituted, saturated or unsaturated hydrocarbon group with 1 to 40 carbon atoms, whereby R1 is not necessarily linked to the nitrogen atom by the COO group, but can be directly linked to the nitrogen atom, R2 is a hydrogen atom, a short chain hydrocarbon group with 1 to 24 carbon atoms, optionally substituted by a hydroxy group, or an aromatic or heterocyclic group, R3 is a hydrogen atom, a straight chain or branched, saturated or unsaturated, hydrocarbon group with 1 to 24 carbon atoms, CaHb represents a direct bond or a straight chain or branched, saturated or unsaturated hydrocarbon group with 1 to 24 carbon atoms and Yn- is an anion with no corroding effect, but rather a protective effect on metals, with the exception of N,N-di(acyloxy-2-ethyl)-N-hydroxy-2-ethyl, N-methyl ammonium-methosulfate, -methophosphate and/or -dimethophosphate.

摘要： An organophilic clay comprising the reaction product of: (a) a smectite-type clay; and (b) a quaternary ammonium compound or compounds selected from the group consisting of: wherein R1 is an alkyl or aralkyl- ester group having 8 to 30 carbon atoms and R2, R3 and R4 are independently selected from the group consisting of (i) R1, (ii) long chain linear or branched alkyl (including methyl), aliphatic or aromatic groups having 1 to 30 carbon atoms (such groups can also include hydroxylated groups); (iii) aralkyl groups, which are benzyl and substituted benzyl moieties, including such groups having fused ring moieties having linear chains or branches of 1 to 30 carbon atoms; (iv) aryl groups such as phenyl and substituted phenyl including fused ring aromatic substituents; (v) beta, gamma unsaturated groups having six or less carbon atoms or hydroxyalkyl groups having 2 to 6 carbon atoms; and (vi) hydrogen and M is an anion selected from the group consisting of chloride, methylsulfate, acetate, iodide and bromide. The organophilic clay is used in a non-aqueous fluid system such as paints, inks, and coatings to provide rheological properties.

摘要： Disclosed is a process for preparing aqueous, clay-based muds, not aggressive to layer clays, which process comprises a first step in which clay is treated with an aqueous solution containing the necessary amount of dispersant to fluidify the mud; a second step, of separation of so treated clay from the aqueous solution containing any not adsorbed dispersant, and, finally, a step of re-dispersion of so treated clay in water, in order to formulate the mud.

摘要： A method of manufacturing relatively dust-free, water-soluble ammonium humate particles for agricultural, plant growth and drilling fluid viscosity lowering uses and to a method of improving the yield of agricultural and horticultural crops by ammoniating a ground leonardite ore. Ground and at least partially dried leonardite ore is contacted, during or after grinding, with an aqueous solution of ammonia to substantially suppress dust formation resulting from the grinding operation and to render the leonardite ore particles substantially more absorbent to aqueous nutrients and more easily dispersed into soil for agricultural purposes. The ammoniated leonardite ore particles also are more useful for lowering the viscosity of drilling muds and other known uses for leonardite ore. In one embodiment, fertilizers, e.g. , N-P-K additives, can be blended with the ammoniated leonardite ore to further improve the nutrient-supplying capacity of the ground and ammonia-treated leonardite ore. The treatment of ground leonardite ore with ammonia to essentially eliminate dust is particularly advantageous when the ground leonardite ore is mixed with fertilizers, such as N-P-K (nitrogen, phosphorous and potassium fertilizer blends).
摘要翻译：制造用于农业，植物生长和钻井液粘度降低用途的相对无尘的水溶性腐殖酸铵颗粒的方法以及通过氨化研磨的芒硝矿石来提高农业和园艺作物的产量的方法。地面和至少部分干燥的白云母矿石在研磨过程中或之后与氨水溶液接触，以基本上抑制由研磨操作引起的粉尘形成，并使得白云矿矿石颗粒对含水营养物基本上更具吸收性并且更容易分散于用于农业用途的土壤。氨化的白云矿矿石颗粒也可用于降低钻石泥浆的粘度和其他已知用途的白云石矿石。在一个实施方案中，肥料，例如N-P-K添加剂可以与氨化的白杨矿石混合，以进一步提高研磨和氨处理的锂矿矿石的养分供应能力。当将地黄铁矿矿石与N-P-K（氮，磷和钾肥料混合物）等肥料混合时，用碱处理粉碎的白云矿矿石基本上消除粉尘是特别有利的。

摘要： Drilling fluid for drilling of wells is subterranean formations where the weight material includes particles of one or more metals and/or metal alloys, including iron and steel. The particles are preferably formed as pearls (pellets) or are ball-shaped and can be made of stainless steel. The weight material can have a small part of particles made of zinc for cathodic protection of pumps and pipe installations which the drilling fluid is transported through.
